Troubleshooting
Symptom:
■ A shutter closed condition is indicated.
INT LED – Green Interlock Open output – Open
TMP LED – Green Over Temperature output – Open
RDY LED – Yellow Laser Ready output – Closed
SHT LED – Off Shutter Open output – Open
LASE LED – Off Laser Active output – Open
Possible Causes:
■ The Shutter Switch (if equipped) is Closed.
If your Firestar laser is equipped with a Shutter Switch, slide the switch to the Open position. The SHT
indicator will illuminate blue.
■ No voltage applied to Pin 10 (Shutter Open Request) on the User I/O connector.
Check to see that a positive or negative voltage (±5–24 VDC) is applied to Pin 10, Shutter Open Re-
quest, with respect to Pin 11, Input Common, on the User I/O connector (refer to User I/O connections
in the Technical Reference chapter for details). If your system does not provide a Shutter Open Request
signal, connect the factory-supplied Quick Start Plug to the User I/O connector on the laser’s rear panel
or wire your male DB-15 connector so that Pin 11 (Input Common) is jumpered to Pin 12 (Auxiliary DC
Power Ground) and Pin 10 (Shutter Open Request) is jumpered to Pin 4 (+5 VDC Auxiliary Power).
Symptom:
■ Your OEM laser has quit lasing or lasing halted and then restarted. The LASE LED may be Off or On
depending on whether PWM Command signals are being applied, but no fault is indicated.
INT LED – Green Interlock Open output – Open
TMP LED – Green Over Temperature output – Open
RDY LED – Yellow Laser Ready output – Closed
SHT LED – Blue Shutter Open output – Closed
LASE LED – Off or On Laser Active output – Open or Closed
Possible Causes:
■ The remote interlock circuit momentarily opened.
Remote interlock faults are not latched on OEM lasers. This means that if an interlock open fault occurs,
the INT indicator will turn red, the Interlock Open output will Close, the RDY light goes out, and lasing
is disabled. However, if the interlock circuit closes again, the INT indicator will change from red to green,
the Interlock Open output will Open, the RDY light illuminates, and five seconds later lasing is enabled.
Symptom:
■ There is no output laser beam; all LED status indicators are Off.
Possible Causes:
■ No DC voltage is applied.
